Description

The invention relates to military equipment, and in particular to devices for launching guided munitions.

A device is known for launching a guided missile or projectile (RF patent No. 2303235 dated July 20, 2007), selected by us as a prototype, containing a clock mechanism, an “I” circuit, a launching element of launch equipment and elements of a one-time action, which ensure the functioning of the control system equipment rocket or projectile, for example, batteries, gyroscope.

The disadvantage of this device is that when the electric igniter of a single-action element is activated, a short circuit can occur, which will lead to failure of the electric igniters of the single-action elements located after it and non-deployment of their corresponding single-action elements, and, consequently, failure of the ammunition.

Design features and the specifics of the functioning of some single-acting elements, for example thermal batteries, do not allow for complete isolation of the terminals of a single-acting electric igniter from each other and from the housing after they are activated.

The objective of the invention is to increase the reliability of the device by eliminating the case when a short circuit occurs when the electric igniter of a single-acting element causes the remaining electric igniters of single-acting elements to fail and, as a result, munition failure.

To achieve the task in the proposed device for launching guided ammunition, containing a power source, a clock mechanism, an “I” circuit, a starting element of launcher equipment and elements of a one-time action, it is new that a block of contactors containing input and outputs is introduced into the device, each of which contains separate electrical keys controlled by its switching command, the input of the block of contactors connected to the power source, and the outputs to the inputs of single-acting elements and with triggering m element of starting equipment, while the input of the clock mechanism is connected to a power source, and the output of the circuit "And" is connected to the block of contactors.

The proposed technical solution improves the reliability of the guided munition by eliminating the influence of the arising short circuit during operation of an electric igniter of a single-acting element on the operation of other electric igniters of single-acting elements.

The proposed device for launching guided ammunition is shown in figure 1, where 1 is a power source (IP), 2 is a clock mechanism (FM), 3 is a block of contactors, 4 is a parameter control unit (BKP), 5 is an “I” circuit (“ And "), 6 - contacts of the clockwork, 7 - starting element of starting equipment (EE), 7 '- electric igniter of starting element of starting equipment (EE), 8, 9 ... n - elements of single operation (ERD1, 2, ..., n) , 8 ', 9' ... n '- electric igniters of single-acting elements (EERD1, 2, ..., n).

The device operates as follows. When the power source 1 is activated, the voltage is supplied to the block of contactors 3 from the first output, as a result of which it is triggered, the voltage is supplied to the clock mechanism 2 from the second output. 8, 9 ... n. From the outputs of the block of contactors, the voltage is supplied to the electric igniters of the single-acting elements 8 ', 9' ... n '. The output to the mode of single-action elements 8, 9 ... n is controlled by the parameter control unit 4. According to the results of the positive control of unit 4, permission is issued to launch the guided munition at the first output of the “And” 5 circuit. The condition for applying a signal to the electric igniter of the starting element of the starting equipment 7 'and, as a consequence, the launch of the ammunition is the permission of the unit 4 to start and operate the contact of the clock mechanism 6.

In the event that at least one of the conditions is not fulfilled: the single-acting elements 8, 9, ... n enter the operating mode, the signal to the electric igniter 7 'is not supplied, which means a ban on the launch of ammunition.

In the event of a short circuit when the electric igniter is activated, the one-time action element 8 ', 9', ... n ', the one-time action element 8, 9, ... n is normally charged, since all the electric igniters of the one-time action elements 8', 9 ', ... n 'are connected to the independent outputs of the block of contactors 3 for charging the remaining elements of a single action 8, 9, ... n this event does not affect.

The power source 1, the clockwork 2, and the starting element of the starting equipment 7 can be performed as in the prototype. Single action elements 8, 9, ... n are made in the form of a gyroscope, batteries, etc., ensuring the functioning of the equipment of the munition control system. The parameter control unit 4, the “I” circuit 5 represent a general microprocessor and can be performed, for example, on a 1986 BE3T 4245.240-5 microprocessor. The block of contactors 3 can be made from a group of field-effect transistors, for example, transistors 2P7231A9, controlled by a microprocessor.

Thus, the proposed device for launching guided ammunition provides cocking of single-action elements in the event of a short circuit in electric igniters of single-action elements, while realizing an automated sequence diagram for launching ammunition and, as a result, increases the likelihood of a combat mission.
